How are you coming to this conclusion? Between my HD and my FiOS DVR, our family can record 4 different shows at once. With four of us recording shows, we rarely hit conflicts. With many cable shows being broadcast multiple times in a week, 4 tuners can cover a lot of ground. What I would want to see from TiVo is a 4 tuner box that can stream it's content to a non-DVR extender box in real time. I just don't know how they can do that and be competitive with the cable operators. For the extender to be useful, it will need a cable card too. That's an additional monthly cost that needs to be factored in. I don't think you'll see tuning adapters built into the next gen TiVo for a few reasons: Why pass the additional cost to subscribers who don't have SDV? My cable provider doesn't use SDV, why should I have to pay for hardware that I don't need. Each cable company controls the tuning adapter firmware. They push out firmware updates to the tuning adapters just like they update their cable boxes. TiVo ends up subsidizes the tuning adapter development. That's an additional cost that TiVo shouldn't have to pay.
